All tradesmen who subcontract on a construction site of any kind will most likely be registered on the Construction Industry Scheme (CIS). This scheme allows the government to take tax from your monthly wages from your main contractor. Unlike most self-employed people you will be paying tax as you go but you will still be required to complete a UK tax return every before the self-assessment deadline.

When is the CIS self-assessment deadline?

The deadline for paper tax returns has already passed as it was midnight 31^st October. However, most people will complete an online tax return. The deadline for an online tax return is midnight 31^st January 2018. There are penalties if you submit your tax return late so it’s important make sure you do it on time.

What are the penalties?

You’ll get a £100 penalty if your tax return is up to 3 months late. If it’s more than 3 months late you’ll have to pay more. Penalties can be appealed. In fact, we specialise in getting penalties cancelled. But it’s better to make sure you submit you return on time.
